I hope vaapi/qsv by themselves does not consume too much cpu during video operations. Only opengl/opencl performance probably might be not really great ... > > > References: > AV1 Encoding on a Budget: The Intel Arc A380 Approach > > https://medium.com/@contact_45426/av1-encoding-on-a-budget-the-intel-arc-a380-approach-d72367f2f349 > > https://history-computer.com/intel-arc-a380-full-review-of-intels-entry-level-gpu/ > > AV1 fixed-function hardware encoder is included in Alchemist GPUs as part > of the Intel Quick Sync Video core. > https://en.wikipedia.org/wiki/Intel_Arc#Alchemist > https://en.wikipedia.org/wiki/AV1#Hardware > > https://en.wikipedia.org/wiki/Intel_Quick_Sync_Video#Hardware_decoding_and_encoding > > > Terje J.
